Specification forming part of Letters Patent No. 122,504, dated January2,1872.

ing a part of this specification and to the letters of reference markedthereon, in which- Figure l is a longitudinal section of acartridge-shell made according to my invention.

Fig. 2 shows the inode of attaching the cup to` the head. Fig. 3 showsthe cup, wad, Iand head, as secured together when in place within theshell, but secured together by an eyelet in stead of the nipple upon theend of the cup'. Fig. 4 represents the cup with a seat or anvil for thecap spun into the nipple for a center-fire primer. Fig. 5 shows a cupwith a seat or anvil spun. into the nipple and closedl together, andsaid cup secured to the wad and head. Fig. 6 shows a cup Without anipple,.but secured to the `wad and head by an eyelet and an iron disk,also secured in the bottom ofthe cup by said eyelet.

1"ig. 7 shows the shell without the wad and ontside metal covering, inits iirst sta-ge of manufacture, and Fig. 8 shows the same shellcoinpleted.

My invention relates to the construction of a cartridge-shell made ofpaper, or of paper and thin metal combined, whereby the re-enforcing cupis secured direetlyto the head of the shell, with the end of shell, or aportion thereof, close 'ly confined between said cup and head, thussecuring all the separate parts of the shell iirmly together, and alsoforming a perfect gas check. f

VThat others skilled in the art maybe able to make and use my invention,l will proceed to describe the same and it-s operation.

ln the. drawing, A, in Fig. 7 represents the cup, having a nipple, a.,thereon, which cup, wit-hits nipple, is struck or spilli up from thinmetal. A disk, C, is punched out from suitable metal, with a holein itscenter, through which the nipple is inserted, and both being placedwithin theI nmchine. The outer end of the nipple is expanded similar toan eyelet,

thus securing the cup to the disk C, and at the saine time the 'centralportion of the disk is forced in toward the cup, bringing the outerl endof the nipple in a littlel beyond the plane My method of constructing ashell having a cup and head of f the outside of the disk C.

this description is as follows:

' l roll up a paper cylinder in the usual manner upon a mandrel, andthen wind paper around the cup A until of just the size to tit theinside of the shell, and then insert said cup and paper in'to the shell,forcing it to the bottom, as shown clearly in Fig. 7. A Wad, B, is thenattached by inserting the nipple a through a hole in the center of saidwad, the head C is then 'placed uponthe nipple, and the shell being thenplaced in a heading-die, a punch, the body of which tits thebody of theshell l), and having a shoulder at d, the end being a little smallerthan the insidediameter of the cup A, is forced into the shell againstthe bottom ofthe cup'. v This crowds the cup A, wad B, and headC firmlytogether, and

secures them by expanding the outer end of the nipple a; forcesthe paperwhich was wound..

around the cup more closely and compactly around the cup', reducing thesize of the lcup a little, and making a flange at the base ofthe cup, asseen clearly in Fig. 1. Before this last operation is performed,however, of forcing the punch into theshell, a metallic covering, e,'ofsuitable thin metal, is wrapped around the paper shell, and then turnedunder a little,- between the endof the paper shell and the head, so thatwhen .the punch is driven in and the head secured to the cup the turnedend of the metal is held securely between the paper body and themetallic head. Fig. 1 represents a cartridge made as described, inwhiche is the thin metallic covering; D, the paper body 5; A, the cuphavin gthe nipple aV made thereon; d,.the paper wound around the cup; B, thewad between the' cup and the head, and C, the head, and all these partsare secured together by merely eyeleting or riveting the end of thenipple a to the head.

ln a cartridge, constructed as described, a rim fire-primer may he used,and when it is desirable to use a center-lire primer or cap, I spin anannular groove, b, intothe nipple, as shown in Fig. 4, and when the cupand head are forced together, inthe operation of eyeleting or rivetingthe end of .the nipple to the 2 122,504 g l l head, the said groove b ispressed together, forming an internal annular flange, as shown at b, inFig. 5. This flange forms an anvil, which receives the force ofthe blowwhen the primeris struck by the firing-pin.

The thin metallic covering e to the shell may be omitted, if desirable,and also the Wad B 5 but i'n place of the wad I put the cup and itspaper Wrapping into the paper shell, as shown in Fig. 7, and turn underthe lower end D of the'pa- A per/shell, and when the nipple is securedto the head C the end D is turned in and secured firmly between the cupA and head C, and takes the place ofthe wad B, as shown clearly inlvFig.8. l

, The thin metal e may be soldered to the head C, Where the two come incontact, in order to insure greater strength; and, if desirable, theturned in end Dof the shell D, shown in Fig. 7, may be dipped in astrong solution of shellac,

or other equivalent material, before the head C is attached, in order tomake the entire base of the cartridge more firm and more completelyWater-proof. K

.Having thus described my invention, what I claim as new, and desire tosecure by Letters 1. The re-enforcing cup A, having the nipple oreyeleta, with the internal flange or seat b 'made therein, when said cupis secured to the head C, all substantially as described..

2. The combination of the case D, cup A, with its wrapping d, head C,nipple or eyelet a and internal flange D', all substantiallyas and forthe purpose described. f ,Y j
